Lera25 [3.4K]

Answer:

Step-by-step explanation:

f(x)= x/5

To solve for f(100), we substitute 100 for x everywhere in the equation:

f(100) = (100)/5

f(100) = 20

Lisa tapes three 7inch by 9inch pieces of construction paper together to make a happy birthday sign for her mom. She uses a piec

USPshnik [31]

Depends on how the papers are connected. if they are connected with the 7cm side joining each other, use solution one. if they are connected with the 9cm side joining each other, use solution two.

perimeter of edges of sign= 2 [(9x3)+7]
= 68 inches

left over= 144-68
= 76 inches

OR

perimeter of edges of sign= 2[(7x3)+9]
= 60 inches

left over= 144-60
= 84 inches

6x+4y=2 10x-8y=32 what is the exact solution by using elimination

Alexeev081 [22]

First, let's multiply the first equation by two. This is because we have to eliminate either x or y by subtraction or addition so that means either both of the x's or both of the y's in the two equations have to be equal. Thus multiplying the first equation by 2 will give 12x+8y=4.
Next, subtract equation two from equation one:
We get a third equation, 2x-0= -28
Thus, x=-28/2. x= -14
In the same way, to find y, we need to eliminate the x's in both equations. This can be done by multiplying the first equation by 5 and the second by 3
Thus : 30x+20y=10 and 30x-24y=96
Subtracting the second equation from the first, we have 0+44y=-86
y=-86/44
y = 1.96 or 43/22

aliya0001 [1]

Answer:

20 games.

Step-by-step explanation:

Given:

Meredith is playing games at an arcade to earn tickets that she can exchange for a prize.

She has 255 tickets from a previous visit.

She earns 6 tickets for each game she plays.

Meredith needs 375 tickets to exchange for the prize she wants.

Question asked:

How many games does Meredith need to play?

Solution:

Total tickets needed to exchange for the prize = 375

Meredith already have = 255 tickets

More tickets needed = 375 - 255 = 120 tickets

<u>By unitary method:</u>

She earns 6 tickets by playing = 1 game

She earns 1 ticket by playing = $\frac{1}{6}$ game

She earns 120 tickets by playing = $\frac{1}{6}\times120=\frac{120}{6} =20\ games$

Therefore, she needs to play 20 games to earn 120 more tickets.
